It seems like its not even worth the effort to try to get drupal to run there. Since the site has to be live on monday, I employed a crude method that gathers all URL aliases, and a few more paths, and generates a full tree of directories and index.php files to mirror the pathauto links. Break the glass, and use this in case of emergency. [its best to run this on a local machine, btw -- it takes a while, and you'll want to turn up max page execution time up to near 120 seconds and beyond for most sites in the php.ini files.
